Much improved pic jumptable codegen:
Then:
call "L1$pb"
"L1$pb":
popl %eax
...
LBB1_1: # entry
imull $4, %ecx, %ecx
leal LJTI1_0-"L1$pb"(%eax), %edx
addl LJTI1_0-"L1$pb"(%ecx,%eax), %edx
jmpl *%edx
.align 2
.set L1_0_set_3,LBB1_3-LJTI1_0
.set L1_0_set_2,LBB1_2-LJTI1_0
.set L1_0_set_5,LBB1_5-LJTI1_0
.set L1_0_set_4,LBB1_4-LJTI1_0
LJTI1_0:
.long L1_0_set_3
.long L1_0_set_2
Now:
call "L1$pb"
"L1$pb":
popl %eax
...
LBB1_1: # entry
addl LJTI1_0-"L1$pb"(%eax,%ecx,4), %eax
jmpl *%eax
.align 2
.set L1_0_set_3,LBB1_3-"L1$pb"
.set L1_0_set_2,LBB1_2-"L1$pb"
.set L1_0_set_5,LBB1_5-"L1$pb"
.set L1_0_set_4,LBB1_4-"L1$pb"
LJTI1_0:
.long L1_0_set_3
.long L1_0_set_2
